In a study published in Sports Health, Master et al. found that the existence of pre-injury mental health diagnoses correlated with longer concussion recovery time and increased emotional symptoms.

A study found that athletes who used cannabis regularly had better eye focus ability and lower levels of brain inflammation compared to the non-cannabis group after repetitive subconcussive head impacts.

A study conducted by Jacob Kay et al. found that male and female teenagers who reported a history of concussion in the last year were at greater risk of suicidal ideation, planning, and attempts than those who had not sustained a concussion in the previous year.

E-scooter injuries in children and adolescents are “becoming much more common and increasingly severe,” according to a 10-year study.

Ian K. Chun found that turf fields result in impact deceleration “as much as 23 g higher on artificial grass compared to natural surfaces.” The higher g forces may translate “to a theoretical increased risk of concussion due to contact with playing surfaces,” according to Chun.

A study found that very low and very high screen time predicted more severe postconcussion symptoms in the first 30 days post-injury. However, this association was no longer present once patients were more than 30 days out from their injury.

A study found a significant reduction in symptom relapse rates related to premature Return to Learn but not for Return to Play, indicating the need for more emphasis on implementing Return to Learn protocol.

Researchers found changes in menstrual patterns 3-4 months post-injury in 1 out of 8 adolescent patients. The authors also found higher symptom severity for those who sustained a concussion after ovulation and before menstruation.

A study found that “youth who experienced a concussion were more likely to develop mental health issues, self-harm, or psychiatric hospitalization than peers who had an orthopedic injury.” We include information and tips for parents.

A study found that patients’ expectations of their recovery duration had a larger impact on their mental health than their actual reported symptoms, number of concussions, or history of mental health concerns.

A study found significant disparities in diagnosis and outcomes between children presenting to a pediatric hospital with assault-related (ARC) and sports-related concussion (SRC).

A study found significant gaps in school-based concussion education in a scoping review, "including a lack of clear guidelines for concussion education content, questionable sustainability of the education delivery and the need for long-term evaluation of outcomes.”

A study has found that for youth ages 10 to 18, “Resuming non-contact physical activity 72 hours after a concussion is safe, and may also reduce symptoms and the risk of delayed recovery,” according to a CHEO Research Institute press release.

A study found that children and adolescents who sustain a concussion are at an increased risk of developing mental health issues. The results indicated that "young people who sustain a concussion are at a 40% higher risk of mental health issues, psychiatric hospitalization, and self-harm compared to those who sustain an orthopedic injury."

PedsConcussion, a living guideline for concussion treatment and recovery for kids and teens, has updated its guidelines for returning to school. The guideline now states that students can return to school when cognitive activities do not make symptoms worse, even if symptoms are still present.

A study. found connections between pre-injury anxiety, post-injury anxiety, and persistent post-concussion symptoms. Dr. William Barr (NYU Langone Health) notably tweeted about the study, commenting: “assessment of anxiety is important among adolescents presenting for concussion care and delivery of evidence-supported treatments for anxiety are important considerations …”

A study conducted by Stephen C. Bunt et al. found that low resilience was associated with a greater number and increased severity of symptoms three months following a sports-related concussion (SRC).

A study conducted by Theodore Macnow et al. found that patients who limited their screen time following a concussion recovered faster than those permitted unlimited screen time.

A study of concussion patients to determine the impact of “initiating physical activity as soon as 24 to 48 hours after concussion to reduce persistent postconcussive symptoms.” They found that adolescent concussion patients who initiated physical activity before their first clinic visit (clinic visits were an average of 9.8 days after concussion) were better off.
